IMPROVEMENT IN GATES.

Specification forming part of Letters Patent No. 192,971, dated July 10,1877; application filed February 3, 1877.

To all whom it may concern:

Be it known that I, JONATHAN BUNDY, of

Oentredale, in the county of Cedar and State specification, and to theletters and figures of reference marked thereon.

Figure l of the drawings is a representation of a side view of myfarm-gate, and Fig. 2 is an end view thereof. Figs. 3 and 4 are detailviews of the same.

This invention relates to farm-gates; and consists in theconstructionand arrangement hereinafter particularly described.

In the accompanying drawings, A designates the sills of the gate-postsB. Said posts are arranged in pairs at each end of the gate, with aspace between each pair, as shown in Fig. 2, and those of each pair areconnected by a cross-piece, 1), near their tops. 0 desig nates a longguide-bar, which extends across I the gateway D at a sufficient heightto avoid injuring vehicles passing through the same, and is connected atits ends to said cross-bars b b. On said guide-bar 0 runs a roller, E,which is journaled between lugs or bearings F F on the upper end of abar, G, whereby the front end of gate H is suspended. The rear end ofsaid gate is provided with a similar roller, I, turning between beariugs I I, secured to said gate, and serving to suspend the same. Saidroller I runs upon a second guideway or guide-bar, J, lower thanguide-bar O, and supported at one end by a standard or post, K, and atthe other end by a crosspiece, b, connecting the nearer pair ofgateposts B.

To the cross-pieces b and b of said nearer pair of posts two horizontalbearings, L L,

are secured, and in these bearings a vertical drum or cylinder, M, isjourualed. On each side of saiddrnm and beyond the gate-posts stands apost or upright, N, bearing at its upper end a guide-board orguide-block, O, which is provided with two diagonally-oppositeperforations, o o. P designates the operatin g-cord of the mechanism,which passes back from suspending-bar G to and around drum M thencethrough perforations 0 o in one of the guide-hoards O; thence to andagain around drum M; thence to and through the perforations in the otherguide-board; thence to and around said drum again, and finally to therear end of gate H, where it is secured to one of the bearings 1.

(lord P thus forms two depending half-loops, one of which is on theoutside of each guideboard or guide-block O and upright N. On each suchdepending portion or half-loop is hung a weight, P.

When the gate is to be opened, one side, 1), of said loop is drawn upon;when the gate is to be closed the other side, 19, is similarly pulled.The gate may thus be caused to slide open on approaching from eitherside, and closed after passing through. The said weights P keep the cordtaut, and in windy weather detachable wooden pins or hooks Q may beemployed to prevent said cord from swaying. Said pins are passed intoperforations' it of posts or uprights N.

Instead of one continuous cord, P, two or more may be employed,connecting the various parts of the apparatus, as above described.

The rail h of gate H is guided by small vertical rollers R R, which aresupported by the gate-post sill A nearest to drum M. Rollers E and I arecircumferentially grooved and flanged to keep them upon their respectiveguideways or guide-bars. I

The said gate H may be fastened automatically in any suitable manner.For instance, roller E, on passing a certain point, may drop into arecess or indentation of guide-bar G, or an L-shaped catch carried bysaid gate may engage with a horizontal cross-bar secured to the frontpair of gate-posts B.

The arrangement of guide-rollers R R and rail h is shown in detail inFig. 3. Fig. 4 shows one of the weights P and a part of cord P securedto one of the posts N by a hook or pin, Q, as stated.

What I claim as new, and desire to secure by Letters Patent, is-

l. The combination of sliding gate H with drum M, perforatedguide-boards 0 O, cord In testimony that I claim the above I have P,and'weights P P, as specified. hereunto subscribed my name in thepresence 2. The combination of sliding gate H with of two witnesses. 7
